This is specific for GCC, but totally harmless for any other C compiler:
GCC accepts 'fall thru' comments from the CWEB sources with its option
'-Wimplicit-fallthrough=2', when we push these comments over to the
tangled C code.

Without affecting CWEB in TeX Live, various array sizes in 'original'
CWEB (release 4.6.1) were increased so that both CTANGLE and CWEAVE (but
unfortunately _not_ CTWILL) can process CTEX.W in Martin Ruckert's WEB2W
project (https://w3-o.cs.hm.edu/users/ruckert/public_html/web2w/index.html).

Major changes since CWEB 4.5:
* Restore '\T' macro backward compatibility.
CWEB 4.3 introduced a major change in the '\T' macro to allow C++ 'hex
exponent' notation (e.g., 0x1FFFFp10). This made CWEAVE/CTWILL mutually
incompatible with non-matching versions of their set of macros and v.v.
This release tries to reestablish the standard behavior at least for
numeric constants. Of course, 'old' CWEAVE/CTWILL won't deliver on 'hex
exponents' in the CWEB input, but those should be rare anyway.
* Restore 'classic' PDF page dimensions.
Heiko's PDF files of 2014 used 'Executive' page dimensions, i.e.,
7.5in times 10in. C/WEB's internal inch values suggest to use those
plus a 0.5in border on each side.
* Revert meaning of option 'c'.
Option 'c' is OFF by default to avoid spurious entries in build.log.
* 'squash'/'reduce' have been straightened out for k=1,..,4.
* Code beautifications for 'make fullmanual'.
* Code cleanup for internal reasons.
* Cleanup in 'prod.w' (indentation et al.).
* New 'prod-cweave.w' (along 'prod-twill.w') for material from CWEBbin.
* Fixes for option '-o' (didn't work as advertised in border cases).
* New signature for the 'make_ministring' function in CTWILL.

When the CWEB programs are called with option '-c' (the default), no
intermediate output files are created at all. After thoroughly testing
these programs, I'll prepare the final release of CWEB 4.6 in the coming
weeks (months).

This is a service release for CWEB 4.0.
* Upstream CWEB 4.5 was reviewed with the 'splint' utility. This
resulted in lots of cast changes and a few code improvements.
* All 'length' variables are retyped to 'size_t'.
* <stdbool.h> is replaced by <kpathsea/simpletypes.h> to keep CWEB
compatible with antique systems that still support TeX Live.

This is yet another service release for CWEB 4.0.
* Upstream CWEB 4.4 has been reset to the original buffer sizes
of CWEB 3.64c. These are now also used in stand-alone CWEBbin.
CWEB for TeX Live uses extended/maxed-out buffer settings.
* A few minor typographical bugs were fixed.
* Tons of minutiae were addressed in the 'fullmanual' documents.

This release is almost the same as CWEB 4.3 of 2021-04-16, but
* it fixes the indexing bug in CWEAVE/CTWILL that got retracted
* it extracts and collects all additions made in CTWILL, so that the
section numbers of CWEAVE are retained up to §272 and new material is
described in the (first) appendix, including the CTWILL user manual
* it provides fully revised and (hopefully) corrected mini-indexes for
CTWILL, if it is processed by itself (to be published in package
'knuth-pdf' on CTAN)

This reverts commit 3ccac2a7d0f4a19dde861c6f4c178e853d90f0cc.
CWEB 4.3 is seriously broken.

This release introduces new features to CWEB 4:
* Former option '-t' is now called '-c'.
- New option '-t' for CWEAVE when dealing with 'typename' in
C++ templates.
- New option '-k' for CTANGLE to keep '-separators in numeric
literals.
* Support for "variadic macros" along "variadic functions".
* @d is printed similar to #define (and vice versa):
- '#' is no longer printed in boldface.
- Spacing is similar in most cases.
* Support for extended C99/C++ numeric literals:
- hexadecimal, octal, and -- new! -- binary numbers.
- NOTE: 'cwebmac.tex 4.3' is NOT compatible with CWEAVE 4.2 and older
and vice versa.
* Long parameter lists in ANSI function definitions are indented similar
to old-style function parameters.
- Option '-i' works similar for old-style and modern function headers.
* Additional C99/C++ keywords -- from 'alignas' to 'thread_local' -- are
supported internally.
* '@i'nclude file 'iso_types.w' for numeric types (in addition to
'c++lib.w').
* Countless code modifications, including some corrections amd
improvements.
Thanks and cudos to Github user "@texdraft" for numerous contributions
to this feature release!

This second service release wraps up the major code overhaul
of CWEB 4.0. New features will take more time.

Enough changes have accumulated since the major release of CWEB 4.0
to warrant a new revision number.

In the course of the "2021 TeX tuneup", Don Knuth kindly transferred
the responsibility for CWEB to me; see the original CWEB home page
(https://www-cs-faculty.stanford.edu/~knuth/cweb.html), section
"CWEB 4.0" and the updated CWEB development project
(https://github.com/ascherer/cweb).
This first new release draws heavily on the multi-decade work collected
in my "CWEBbin" project (https://github.com/ascherer/cwebbin). I moved
(almost) all stuff from the "*-patch.*" changefiles into the new CWEB
sources and applied all of the "*-ansi.*" changes as well.
Moreover, I made "common.h" the full interface of "common.w" in order to
avoid code redundancy. And I tried to fix as many of the bugs reported
by email to DEK and/or tex-k@tug.org.
In total, "make; make cautiously; make fullmanual" runs flawlessly with
GCC on Linux and with LLVM on MacOS.
After the release of "CWEB 4.0", also "CWEBbin 2021" has also been fully
revised. Thousands of lines of changefiles could be purged. What's
left are the clearcut extensions for CWEB and the additional stuff for
integration in "TeX Live 2021".

If disabled with '-t', the temporary output is ignored unconditionally
and the final output is (re-)created irrespective of changes between
runs. (Default is '+t' for CWEB={ctangle,cweave,ctwill}.)
